Abstract
Electrochemical electrodes with self-temperature regulation functionality developed by PCB technology are reported. A two-layer PCB on which electrochemical electrodes in a three-electrode configuration on the top layer and a heater on the bottom layer are designed. The heater warms up the electrochem-ical electrodes and the sample on them, and a controller switching circuit is designed to turn on/off the heater sequentially in order to keep the sample temperature constant at the target value. Cyclic voltam-metry represents the stable performance of PCB-based electrochemical electrodes with both electro-plated gold and ENIG surface finishes at different temperatures. The presented platform has a greatpotential for developing temperature-sensitive chemical/biochemical sensors.
